The BlackBerry6 OS will most likely not be officially released for the 9700. When we do see it, it will probably be a leak. Either way, just keep watching the forums for a BlackBerry 6 build for the 9700. There's no signing up for OS upgrades with BlackBerry. You will have to download and install the OS on your computer, plug in your BB and upgrade.
We pull batteries, swap bezels, break contracts, and stay up all night. We change OSes like we change underwear. If our phones could make us fly, we still wouldn't be satisfied. We're cut from a different cloth. A better breed. We are BlackBerry.
